TO ALL WHOM IT MAY CONCERN.;

Be itr lknown that 11,F1tANz VoEG'rLI, of Montgomery City, in the county ot' Montgomery, and Stato of Missouri, have inventeda newand useful Improvement in Spinning Machines; and I do` hereby declare that the following isa full and clear description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

The subject of this invention is a machine in which the tlax, wool, or other fibrous article to be spun is fed into a double set of revolving rol-Iers driven at different degrees of speed, the said rollers feeding the unspun material into ttf-hollow spindle, from which the thread is conveyed, through'an aperture in its side, to the reel or bobbin, upon which lit -is woundhy automatic machinery. The whole apparatus may be operated by a treadle, the same as that used upon old spinning-wheels.-

,To enable those skilled in the art to construct and use my improved machine, I will proceed to describe its construction and operatioi l u Figure 1 of the drawings is a front elevation of the machine.

Figure 2 is a rear velevation of it,"sho1'vin"'g' 'a portion of"thelramewdr`k broken'out, so as to disclose' the machinery within it.

Figure 3 is a top plan of the machine.

A shelf, A, resting on short legs, A1, supports the entire machine. Erected upon this shelf are two vertical posts, Az A, the top ends of which are secured in theirvrelative positions by a cross-beam 'or cap,-A, immediately below which there is 'a sliding-bea`m, A",-guided by the. two vertical posts. The sliding-beam A is held up in its proper position by means of the screw B, which serves as a. tightener for the belt c that transmits power from the driving-wheel C to the spindle which is att-achedto the sliding-beam. FA brace, a, secured to the bottom of the extending end of the beam A, rests against the exterior edge of the post A2, and serves to support the aforesaid beam. The driving-wheel C hasits bearings in the posts A2 A3, and a crank, el, attached to one of its journals is connected, by means 'of` the pitnan C1', `tothe treadle C, which has its bearings in the legs A1. There nre two short projecting arms, A, fixed tothe beam A5, as is clearly shown in iig. 3, which furnish bearings for the hollow spindle D, Spring-followers d press upon' the'journals of the spindle and keep them in their proper positions on their bearings, yet may easily be thrown aside when it is necessary to lift the spindle out of its bearings, which has to be done every time a' newv spool, D1, is to be placed upon the spindle. A groove, dl, turned in the end part4 of .the"sp,ool, furnishes a pulley for the application of the driving-belt c, and the friction of the spool upon the spindle causes the latter to revolve with it. A roller-frame, E, is hinged to one of the arms A6, This frame may be held up in a horizontal position, as is shown in tig. 1, by means of the hook cI which is secured to the frame A, or it maybe dropped down, as is shown in g. 2, by simply disengaging the said hook from the roller-frame. Each of these positions is adapted to a particular operation of the machine, as will be hereinafter more fully described. On the outer end of the frame E there are two pairs of rollers, e2 and e, which are driven by means ot" the belts c* and c5 from the counter-shaft E,`which is also located upon the same frame. On each end-of the'counter-shaft VEl there are cone-pulleys for the belts Ac and c5, and there are. also corresponding cone-pulleysfor these belts attached to the journals of the rollers e and e. The general construction and arrangement of these cone.pulleys is such thatthe speed of `the rollers may be either increased or diminish'eiat pleasure, but the speed of the rollers e3 will always be faster thanthat of the rollers e2; and by the adjustment of the belts c" c5 to different pulleys this dilferenceof speed may be increased orx diminished, for -the purpose hereinaftcr'oxplained. .A tightencr, E', forced down by the spring c5, is placed on the belts c* c5, so as to keep them always tight. rlfhe 'springs-c7 are attached to links c that connect with the follower-plates c, in which' the journals of the two top rollers {in d their bearings, and serve to hold the said rollers down upon the lower ones so tightly that the friction between the upper and lower roller of each set will cause the upper rollers to' revolve withithe lower ones. The driving-shaft vEl receives its 'motion through the medium of the bevel cog-whcelf,(on its outer end,) -which gearssinto the bevel cog-wheelf" on the end of the horizontal shaft F- which is placed within the beam A". As itis not necessary to run the rollers-when the frame E is thrown down, as is shown in'g. 2, the act of throwing the sadjframe down from its horizontal position disconnects the Wheel f from the wheel.y".v Anl endless screw, f2, on the axle of the driving-wheel, and within the post A,

coms

gears into and communicates motion to thc vertical shaft Fl, also within the said post. The top end of this shaft should be square, so as to allow the bevel cog-wheelf3 which is piaceri thereon to slide up and down with the beam A5, and at all times gear into the bcvel-wheelf, so as to transmit motion to the shaft l". As only a slow feed-motion is to be communicated to the rollers, the combination of endless screw, bevelwheels, and shafts, herein described, is the most simple and desirable that can probably be employed, though the shafts F and Fl might be easily placed outside of the timber-work, with slight alterations and little inconvenience. An endless serew,f5, on the shaft F, communicates a continuous motion to the endless chain (l, shown inside ofthe beam A in iig. 2. A traversing-pin, G, attached to this endless chain, extends va short distance in front of the beam A, and connects with and transmits to the slnlingcarriage H a reciprocatingr motion. The sliding-carriage ll runs upon a track or rod, h, attached to the beam A5. Ain arm, H, attached to the carriage H, extends therefrom to the clutch i upon the spindle, and the said clutch receives a longitudinal reciprocating motion, imparted to it by the said carriage H, which is driven by the pin G, as aforesaid. There are two feeder-rods, g g, attached to the clutch z, that extend outward therefrom a sufficient distance to embrace the thickness of the bobbin to be wound between their horizontal arms, as shown in fig. l. The outer ends of these feeder-rods arc guided by rods g2g, attached to the spindle near the inner end of the spool, and revolved with it. The spindle is hollow from its forward end to near the spool, where a transverse hole, d, opens communication from the interior orifice to both outsidcs of the spindle. These communications with the exterior of the spindle are made in an axial plane coinciding with that in which the perpendicular portions of thc rods g2g leave theY spindle, so that the threads passing out of the orifices d may pass over the grooved sheaves g attached to the guides g2 g3. The direction of the thread is shown by the red line T in fig. 1, and the reciprocating motion of the feeders y g, as already described, is such as to wind the thread regularly around the spool from one end to the other as the feeder or iyer is revolved.

The operation of a machine constructed as above described is us follow's: llhe loose flax, wool, cotton, or other article to be spun into thread, is to be fed by the operator (who stands with one foot upon the treadle) in to or between the rollers ez, and from thence it passes through between the rollers e, and thence through the hollow spindle, by the revolution of which it is properly spun, and is finally carried out of the spindle through the aperture d2 over the sheave g, through an cyelet or hook on the outer end of the feeder g or g, and from thence it is wound around the spool D. As the rollers e3 revolve more rapidly than tho rollers c, the unspun material is pulled out into an even mass between the said rollers. This mass may hc made of the proper size for any required size of thread by reducing` or increasing the speed of the rollers, as already described. In the operation of spinning the roller-frame will be held up in its horizontal position, as shown in fig. 1, but if it is desired to twist two threads already spun together, this part of the machine may be dropped down, as shown in iig. 2, when the threads to be twisted together may be fed directly into thc hollow spindle, after which the rest of the operation will be as before.

Having described my invention, what I claim, is-

1. The combination and arrangement of the parts F, F, f,ffz.f,j", and G, substantially as and for the purpose described.

2. The automatic feeder H Hl, G G', and g gl, to distribute the threads upon the spool D, substantially as set forth.

3. The general combination of all the parts as shown, substantially as and for the purpose set forth.
